IC 3402 is a type Sbc [1] spiral galaxy located 370 million light-years away from the Solar System in the Coma Berenices constellation. [2] [3] IC 3402 has an estimated diameter of 135,000 light-years [3] and was first discovered by a German astronomer Max Wolf on March 23, 1903. [4] It is a member of the Coma Supercluster [5] [6] with recent star formation activity [7] and covering ∼500 deg2 on the sky. [8]
IC 3402 is classified as a thin, [9] disklike edge-on galaxy with a diameter larger compared to a = 40 arcsec and a major-to-minor axis ratio of a/b greater than 7 according to observations made by Palomar Observatory Sky Survey and by the ESO/SERC survey. [10] Moreover, it is also classified as a low-surface brightness galaxy with a V and R local luminosity density of jR=(1.9+/-0.6)×108 Lsolar and jV=(2.2+/-0.7)×108 Lsolar. Researchers who measured its luminosity, found out there is a strong correlation, which color-surface brightness relation is (V-R)0=(-0.11+/-0.05)μR,0+(2.6+/-0.9). [11]
IC 3402 also a box/peanut galaxy making up 22 percent of galaxies with the same morphology, which researchers found the strength of its structure increases slightly by B/T (bulge-to-total flux ratio). [12] In additional, IC 3402 is an isolated late-type galaxy, less massive by 50% and younger (by Hβ) by 20%. [13]
The galaxy is known to host a Type II active galactic nucleus with a luminosity function of 22 μm, which its mid-infrared emission is dominated by its nucleus and not the host galaxy. [14] IC 3402 also has a Tully-Fisher distance, found lying within 15,000 km s-1. Researchers who used the Arecibo Telescope found it has a Hubble Constant value of H0 = 75.1 ± 0.2(stat.), with the potential systematics reaching up to ±3 km s-1 Mpc-1. [15]
IC 3402 is located within 1 Abell radius from the Coma Cluster. The galaxy contains three times lesser of hydrogen levels, indicating there is strong tendency for galaxies like IC 3402, severely H I-depleted to be redder and of earlier Hubble type. [5] Amongst 20% of the galaxies extracted from the ALFALFA 21 cm survey, IC 3402 shows a significant H I profile asymmetry that is 35.2% ± 0.3% single-peaked. This indicates the galaxy has a lower mass. [16]
The Leo Cluster is a galaxy cluster about 330 million light-years distant in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. Along with the Coma Cluster, it is one of the two major clusters comprising the Coma Supercluster, which in turn is part of the CfA2 Great Wall, which is hundreds of millions light years long and is one of the largest known structures in the universe.

NGC 4242 is a spiral galaxy in the northern constellation of Canes Venatici. The galaxy is about 18 million light years away. It was discovered on 10 April 1788 by William Herschel, and it was described as "very faint, considerably large, irregular, round, very gradually brighter in the middle, resolvable" by John Louis Emil Dreyer, the compiler of the New General Catalogue.
The Coma I Group is a group of galaxies located about 14.5 Mpc (47.3 Mly) away in the constellation Coma Berenices. The brightest member of the group is NGC 4725. The Coma I Group is rich in spiral galaxies while containing few elliptical and lenticular galaxies. Coma I lies in the foreground of the more distant Coma and Leo clusters and is located within the Virgo Supercluster.
NGC 3860 is a spiral galaxy located about 340 million light-years away in the constellation Leo. NGC 3860 was discovered by astronomer William Herschel on April 27, 1785. The galaxy is a member of the Leo Cluster and is a low-luminosity AGN (LLAGN). Gavazzi et al. however classified NGC 3860 as a strong AGN which may have been triggered by a supermassive black hole in the center of the galaxy.
NGC 4060 is a lenticular galaxy located 320 million light-years away in the constellation Coma Berenices. It was discovered by astronomer Albert Marth on March 18, 1865 and is a member of the NGC 4065 Group which is part of the Coma Supercluster.
NGC 4061 is an elliptical galaxy located 310 light-years away in the constellation Coma Berenices. It was discovered by astronomer William Herschel on April 27, 1785. It was rediscovered by John Herschel on April 29, 1832. It is listed both as NGC 4061 and NGC 4055. NGC 4061 is a member of the NGC 4065 Group and forms an interacting pair with its companion, NGC 4065 as evidenced by distortions in their optical isophotes.
NGC 4066 is an elliptical galaxy located 340 million light-years away in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on April 27, 1785. NGC 4066 is a member of the NGC 4065 Group.
